Rename the ioctl asic register and slot macros from ASIC_<xxx> to
IOASIC_<xxx>, to be compatible with the machine-indpendent names in
sys/dev/tc/ioasicvar.h. The pmax code still uses
sys/arch/pmax/pmax/asic.h, as some of the registers and offsets
defined there are not yet defined in sys/dev/tc/ioasicvar.h.
Rename the ioctl asic base-address pointer from `asic_base' to `ioasic_base'.
Use the device address in the attach_args structure, instead of
using the deprecated BUS_CVTADDR macro.
Change the Mach derived asc driver to use "SCSI_PHASE_xxx" instead of
"ASC_PHASE_xxx", as the latest version of the Mach driver does.
Several had: _MACHINE_ICU_H_ -> _NS32K_ICU_H_
cpu.h * Removed definition of cpu_swapout.
* Added definition of cpu_wait.
frame.h * added struct switchframe
icu.h * tweeked ints_off
param.h * More derived constants.
* Alot of things taken over from i386/include/param.h.
pcb.h * Removed pcb_flags (was unused) and pcb_pl.
The current priority level is now stored
in the switch frame by cpu_switch.
pmap.h * Taken over from i386/include/pmap.h.
psl.h * Add USERMODE definition
trap.h * T_INTERRUPT -> T_AST
types.h * Remove __FORK_BRAINDAMAGE
vmparam.h * Taken over from i386/include/vmparam.h.
Added definition of INTSTACK.
clock.c * Removed definition of DELAY.
intr.c * Removed an unneeded $Id:....$
locore.s * Moved some of the low level initialization
code to machdep.c.
* Defined proc_trampoline.
* Changed sigcode to pass scp to SYS_sigreturn.
* Changed copyin/copyout/fu*/su* to take advantage
of the ns32532's dual address instructions.
* Recoded copyinstr/copyoutstr/copystr in assembler.
* Added a new and faster version of bzero.
This makes bzero.s unnecessary.
* Defined suswintr to make profiling work.
* Recoded cpu_switch modelled after the i386
version of cpu_switch.
* Added support for lazy fpu state restore to
cpu_switch.
* Recoded trap handling code to be more readable.
* Added experimental code for single cacheline
invalidation.
machdep.c * Copied over cpu_startup from i386/i386/machdep.c.
* Changed sys_sigreturn to take advantage of the
argument passed by the trampoline code.
* Changed boot to call doshutdownhooks and to store
machine state in case of a panic.
* Changed setregs to clear the fpu registers.
* Recoded low_level_init. It's now called init532.
* cpu_reset: New function, resets the machine.
trap.c * Pulled over from i386/i386/trap.c.
* Added support for lazy saved/restored fpu state.
vm_machdep.c * Removed kstack double mapping by pulling over alot
of code from i386/i386/vm_machdep.c.
* Added support for lazy saved/restored fpu state.
* Moved freeing of process resources from cpu_wait
to cpu_exit.
* Pulled over cpu_coredump, pagemove, vmapbuf and
vunmapbuf from i386/i386/vm_machdep.c.
pmap.c * Pulled over from i386/i386/pmap.c.
genassym.c * Removed old and unused definitions, added new ones.
sys_machdep.c * Moved sys_sysarch from machdep.c to sys_machdep.c.
process_machdep.c * Changed to work without ktack double mapping.
* Changed to work with lazy saved/restored fpu state.
Rename the ioctl asic register and slot macros from ASIC_<xxx> to
IOASIC_<xxx>, to be compatible with the machine-indpendent names in
sys/dev/tc/ioasicvar.h. The pmax code still uses
sys/arch/pmax/pmax/asic.h, as some of the registers and offsets
defined there are not yet defined in sys/dev/tc/ioasicvar.h.
Rename the ioctl asic base-address pointer from `asic_base' to `ioasic_base'.
independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h:
* Change the tc autoconfiguration tables to use a struct tc_attach_args
instead of the ad-hoc structure.
* Change all pmax device drivers to use a `struct confargs' that's
assignment-compatible with sys/dev/tc/tcvar.h `struct tcdev_attach_args'.
Devices that can be present on a TC or as ioctl asic/mainbus builtins
use the same `struct confargs'.
* Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from
an old, now-obsolete sys/arch/alpha snapshot.
* Update the comments and debugging code in interrupt handlers to
be consistent with the machine-independent TC support.
Other commits that overlap the same source files include: re-enabling
clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.
